The third stimulus payment is on its way to taxpayers that qualify based on level of income. Payments will begin to be reduced for individuals making $75,000 or above in Adjusted Gross Income ($150,000 for married filing jointly.) The reduced payments end at $80,000 for individuals ($160,000); people above these levels are ineligible for a payment.
As mentioned in the IRS communication, “… in general, most people will get $1,400 for themselves and $1,400 for each of their qualifying dependents claimed on their tax return. As with the first two Economic Impact Payments in 2020, most Americans will receive their money without having to take any action. Some Americans may see the direct deposit payments as pending or as provisional payments in their accounts before the official payment date of March 17.
Because these payments are automatic for most eligible people, contacting either financial institutions or the IRS on payment timing will not speed up their arrival. Social Security and other federal beneficiaries will generally receive this third payment the same way as their regular benefits. A payment date for this group will be announced shortly.”
